Fixing "Dangerous Site" Warnings on GitHub Pages – A Complete Guide

If you’ve ever hosted a clone project (like Netflix, Spotify, or Twitter) on GitHub Pages, you might have faced a frustrating issue—Google marking your site as "Dangerous" with a red warning page. This can affect not just your hosted project but also your GitHub profile and other repositories.

In this blog, I’ll explain why this happens and how to fix it permanently. 🚀

Why Does Google Flag GitHub Pages as "Dangerous"?

Google flags websites as unsafe when they detect:

1️⃣ Copyright Violations – If your project closely resembles a brand like Netflix, it can be flagged for impersonation. 2️⃣ Phishing or Malware Risks – If your site has unverified scripts or mimics a login page, it could be labeled deceptive. 3️⃣ Unsecure Connections – Hosting external resources without HTTPS can trigger security alerts. 4️⃣ User Reports – If multiple users report your site as unsafe, Google may block it automatically.

Once flagged, your GitHub Pages link will show a red warning page with messages like:

🚨 "Deceptive site ahead" 🚨 "This site may harm your computer"

Your GitHub repository links might also appear risky to others.

🔥 The Best Solution – Delete & Reset

If your site has already been marked unsafe, follow these steps to fix it permanently:

1️⃣ Delete the Repository

• Remove the GitHub repository hosting the project.

• If possible, delete any similar repositories with cloned content.

2️⃣ Change Your GitHub Username

• Go to GitHub Settings > Account > Change Username.

• This resets your profile’s reputation and removes flagged connections.

• Example: If your username is john-dev and Google flagged your profile, change it to john-code or something different.

• This prevents Google from linking the flagged content to your new profile.

3️⃣ Wait for Cache Clearance

• Google and GitHub may take a few days to remove the warning from their records.

• You can check your site’s safety status here: Google Transparency Report

4️⃣ Re-upload With a Unique Name

• If you still want to showcase your project, rename it to something original.

• Example: Instead of "Netflix Clone", use "MovieStream UI" with a fresh design.

5️⃣ Request a Google Review

• If your site is still flagged, go to Google Search Console and request a security review.

• Google will check your site and remove the warning if it's safe.
